First, go get yourself a pair of boots or hard soled shoes. Kicking that thing with sneakers is not good for your feet.
Second stop kicking that bike on the sidestand. They are not meant for that. Kick it with the bike resting on the tires and no stands.
Third, unless you put aftermarket carbs on the bike with accelerator pumps, twisting the throttle before you start it does absolutely nothing. You've been watching too many Harley riders.
My opinion on why the bike is not starting is you are not getting enough gas. It's hard to see from the vid, but it appears that you are tickling it, which floods the engine a bit and right after that she fires and runs for a few seconds. That tells me it is running out of gas.
I also notice that you only tickle one carb. Do them both. Both cylinders need gas.
It might want to be choked. If you still have the chokes installed, use them. My T140V will not start unless I choke it, tickled or not. Your's could be the same.
If you have no chokes, then you may have to tickle it excessively to get her to run.
You might not be getting any fuel thru the idle circuit.
You might also have your throttle slides closed down so far that it is not getting enough air/fuel. Open them up a bit. You can always lower them if the idle is too high.
Or, you may be opening up the throttle when it starts and that is killing it. Try leaving the throttle alone and see if she will start and settle into an idle before you start to whack open the throttle. If she is not getting enough gas, opening the throttle does not help.
